Those conditions might be minor, but in practice, the effect might be so interwoven into the psychology of the person that it is difficult to detect, outside of irrational behavior.
When the chemicals associated with fear in the blood are detected by the protozoa, it releases an enzyme that causes the brain to secrete both dopamine, the “pleasure” chemical, and GABA, the “awake/sleep/drowsiness” chemical.
Thus instead of a proper fear response, they feel a sense of pleasure, even sexual pleasure, and are in a half awake, half sleep state of mind. The GABA effect can also be caused by “hypnotic” drugs.
So why, for example, are liberals attracted to the enemies of America, be they communists, Nazis, or fanatics? And why also are they adamant that America must be incapable of defending itself against attack, be it through unilateral disarmament or abandoning its missile defenses?
This latter raises a rather dire point. That is, if liberals were just self-destructive, it would be one thing; but they almost seem to worship at the altar of death, in wanting to have everyone killed.
Except for the most heinous of murderers, that is. They want them spared. Yet another twist.
This is cool—I never thought that my post would end up generating a scientific debate on biochemistry. Interesting!
